PORTABLE FOLDABLE CONVEYER.

Application filed September 22, 1524. Serial No. 739,072.

This invention relates to portable conveyers and the like, and particularly to a conveyer for elevating sand, gravel, coal or Similar granular materials.

I The prime object of the invention is to design a conveyer which can be compactly folded so that it can be easily transported from one location to another.

Another object is to provide a simple and practical conveyer which can be quickly folded and unfolded, and which can be quickly set at any desired angle of inclination.

A still further object is to provide an improved supporting and balancing means whereby both side and end thrust is eliminated, and whereby the conveyer can bev quickly raised or lowered as desired.

A further object still is to provide a flexible drive to allow the conveyer to be driven regardless of the height or angle of inclination, and which also allows the conveyer to be folded without in any manner interfering therewith.

The above and other objects will appear as the specification progresses, reference being had to the accompanying drawings in which likereference numerals indicate like parts throughout the several views thereof.

In the drawings.

Fig. 1 is a side view of my improved portable foldable conveyer showing the conveyer folded and the belt removed.

Fig. 2 is a side view showing the conveyer 35 set up for use.

Fig. 3 is a fragmentary cross sectional view of the truck illustrating the conveyer driving mechanism.

Fig. 4 is a front view of one of the booms.

Fig. 5 is a cross sectional view of the conveyer, also illustrating one of the. return rollers.

Fig. 6 is a fragmentary detail of the top of the mast and showing the sheaves mounted thereon.

Fig. 7 is also a fragmentary view of the mast, parts being broken away to show the rollers.

Fig. 8 is a fragmentary sectional view illustrating the manner of leading the cables to the sounding drum.

-Fig. 9 is a side view of one of the anchor plates.

Referring now particularly to the drawings in which we have shown the preferred embodiment of our invention, the numeral 1 indicates a frame supported on ground engaging wheels 2 in the usual manner, a mast, comprising a pair of spaced apart channels 3 and 4 is mounted on the side members of the frame at the center, being braced by the members 5 and the longitudinal brace 6. The upper ends of these channels being connected by a section of shafting 7 on which a plurality of pulleys are rotatably mounted. Anchor plates 8 are also mounted on this shaft and to which the adjusting cables are anchored in a manner to be presently described. A motor 9 is mounted on the frame and spaced apart bearings 10 are secured to each respective corner as shown, and a shaft 10* is mounted therein, individual booms 11 and 11 respectively being pivotally mounted on this shaft at the frontand rear, the upper ends of each boom being connected by means of a shaft 12 on which a plurality of sheaves 13 are mounted, the sides of said boom being reinforced by the braces 14. the lower ends of which are mounted on the shaft 10 the upper ends being riveted or otherwise secured to the boom intermediate its length.

The conveyer comprises a number of sections 15 having plates or similar members 16 secured to the ends of each section. these plates being pivotally connected by the pin 17 to form a hinge, and when in set up position a similar pin 18 is inserted in suitable openings 19 provided in the lower portion of the plate, thereby locking the sections rigidly together and forming a strong rigid structure, each section comprises a plate 20 having the reinforcing channels 21 secured to the edges thereof. Spaced apart boxes 22 are secured to the face of the plate, and rollers 23 are revolubly mounted thereon, return rollers 24 being setin suitable bearings 25 secured to the side channel members 21 on the underside of the plate 20. Rollers 26 are provided on one end of each end section, and are mounted in a take-up 27 which is slidably secured to the one end of each end section and we do not deem it necessary to describe this in detail as the take-up can be of any desired construction, such as commonly used for this purpose.

The conveying belt 28 is trained over these end rollers 26 and rides on the rollers booms and ,controllingthe angle of inclination of the conveyer accordingly.

The conveyeris supported-bymeans of cable or rope slings 29 suitably-anchored one on ,each' side ofxthe conveyer sections at the points "30,'these'being trained over the sheaves 13 and 13 which are rotatably mounted on the upper end of the boom ll. The boom is in turn held by cables 31 and 31, the one end ofeach cableb eing'secured to an anchor plate 8 carried by the mast, the cable 31 on. the" far side of the. machine leading over and around one or the sheaves 32, which aren'iou-nted"on'the.boom, and 15- thence back and around the sheave .33, leading down and around ,the-sheavesfit and '34? .respectively which are mounted on brackets secured'to the frame, andithence 'leading'to .and being.'wound on adouble drum '35.
